Having produce on hand will ensure that your cooking always has a burst of freshness. Since some of these ingredients will expire quickly (like avocados), just buy what you'll need, or store in the refrigerator until ready to use.
Since it will take a long time for these ingredients to expire, it's easy to just keep a can of each in your pantry. And if you don't use the entire can, you can store some ingredients—like sweetened condensed milk—in the refrigerator for up to three weeks.
Spices are some of the most important ingredients in Mexican cuisine. Keep these different spices on hand in your pantry to ensure that your cooking is always flavorful and never bland.
These ingredients will help add flavor to both main dishes and baked goods. You can keep most of them in your pantry, but it's best to keep some—like salsa and picante sauce—in your fridge after opening.
You definitely want to keep these ingredients on hand: They can be used in a variety of different recipes, from breakfast to dessert.
These other items are great to have on hand, either as a vital part of your Mexican pantry or to accompany Mexican meals. Store most of them in your pantry or fridge—but if you want to make your tortillas last longer, stack them between two layers of waxed paper and store in a freezer bag. Both homemade and purchased tortillas can be frozen for up to a month.
